25,678 rounded to the nearest 10,000 would be 30,000
Hello there!
Start by asking yourself:"How to find the percentage of a number?"
We need to use the equation y = P% * x
In this case, the y is 20%
Y = P% * X
Y = 20% * X
Now we need to convert the percentage to decimal
P = 20%/100
P = 0.2
Then go back to the equation
Y= 0.2 * 5
Y = 1
The answer is 1
I hope the steps are easy to understand and hopefully the answer helps!
As always, I'm glad to help you today!
Answer:
Step-by-step explanation:
1. sinФ = cos 25
25 ° is in the between 0 and 90°
therefore it can simply represent
cosФ= sin (90-Ф) = sin (90 - 25) = sin 65
2. sin(Ф/3 + 10) = cos Ф
cos Ф = sin (90 -Ф)
sin(Ф/3 + 10) = cos Ф
sin(Ф/3 + 10) = cos Ф = sin(90-Ф)
Ф/3+10=90-Ф
10Ф+3/30 = 90-Ф
10Ф+3 = 30(90-Ф)
10Ф+3 = 2700-30Ф
10Ф+30Ф=2700-3
40Ф = 2697
Ф = 2697 / 40 = 67.425 ≅ 67.4°
